Try going without a cell phone or television?
I’ve never had a cell phone in my life and I cancelled my television service in 2009.
Life is good!
For those with open communications (no encryption) a simple code book can be constructed using letters and numbers. In short, these letters and number combinations are used to substitute for words. Such codes are not very secure as repeated use will allow for code breaking techniques to figure out the code. However, they are more than enough to defeat most non government attempts to listen in.
The building of such code book allows for 260 different slots to be filled with important words. With that in mind, the words should be important words to your situation and location. For example, “farm” is listed as the 1256th most frequent word. However, it might be the name of your secure / bunker location. As such, you may want to include that in your list of 260 words. This list is something that you should develop on your own.
Using a letter/number allows for 260 code words. Simple but somewhat limiting. Using Letter/Letter such as BZ or PF allows for a much larger code set (676) but it also makes for a much larger code book that must be printed / carried by each user.
Once you have this list of code words, they need to be assigned a letter/number combination assuming the simple system. For example M3 might be the value of “farm”. And P8 might be the value for “ASAP”. Thus your transmission might be ... You need to get to M3 P8.
The advantage of a code book is that only the people who have the code book can easily decipher the message. However, this is also the weakness of a code book. It requires the distribution of the actual book to all endpoints. Also, if a code book is lost or compromised, the code book will need to be altered.
Thanks for the post.
Believe in COMMS. Loaded with radios and most of them have been jacked with one way or another.
Have one that has been opened up that I run on my 4wheeler down south that will put out 50w GMRS/FRS.... It also does all the freqs of CSO, DPS and (others). Can actually talk on these bans as well but I DO NOT DO THAT!!!! It is also Ham 2m and I believe 7m(?) All of this at 50w. Most radios can be opened up like this with a few added jumpers.
Then a hand held (Yaezu 7VXR) that is also opened up that can do basically do the same but is also a scanner.
Then the ol reliable CB. Gotta have one of those.
First, a little history. Last year I rode my motorcycle a thousand miles to Washington DC for the Sept. 11 "2 million bikers to DC" ride. COMMS were a hot topic among the group that I rode with and many of the new friends I made on this trip. So, when I returned to Florida, I dug out my old CB radios that had been stored for 30 years and set up a mobile and base. The mobile has SSB (single side band) and because of the solar cycle, every morning on the way to work, I could hear traffic from Europe and every evening I could hear traffic from the west coast and when conditions were very good, I could hear Hawaii. That was usually channel 38 lower side band.
Next, I talked with some close friends that have an audio/video repair business about my antennas and all of them were hams. They showed me a dual band, hand held (HT) Boafeng UV-5R that cost about $35 delivered, gave me a Technician class study manual and showed me the online study guides and self testing programs. I ordered the Boafeng as they don't require a license to listen, only to transmit and began my studies. The local ham club has repeaters and gives the license tests for free once a month. By the first of December, I had my Tech license and was on the air with the local hams and by Jan of this year I earned my General license and bought a 30 year old HF radio for $400 and put up a $50 antenna and have been making world wide contacts.
So, a year ago, I rode my bike a couple days with thousands of patriotic Americans and discussed this topic and after some study, a little effort and maybe $800 investment, I have local and world wide COMMS.
Last night, I attended our county ARES (Amateur Radio Emergency Service) monthly meeting. I live in the center of Florida in a huge county and if our repeater towers go down we have to make contacts long distance on the VHF/UHF bands. The typical cheap hand held radio is reliable only for a few miles (3 to 5 miles on simplex). The HF bands skip over local contacts in the daylight hours and we have found through exercises that 2 meter SSB (single side band) simplex gets the best results but requires a more expensive radio. Contacts were made 17 to 20 miles consistently. As you can drive 75 miles and still be in our county, relays are a must so we can pass messages. Our desire is to have hand held radio coverage of this huge county, but without enough relays, it won't be possible.
So, the article listed has some great info, but without some study, practice and investment, COMMS are going to be very limited.
Here are a few links for someone interested in Amateur Radio:

Note: The ARRL is celebrating it's 100th Anniversary this year. Also, I found many of the study guides I needed to pass my exams at local libraries by a simple search on ARRL.

Online Ham selftest You will have to create a free account to practice the Ham test so it can tract your individual results in areas you need to work on so you can pass your exam easily. (I used this one.)
Becoming a Ham This page has other online study info and a lot of great links. (Some of the links are broken and some of the study guides require payment while others you don't even need to create an account.)

Well, I warned you this would be a long post but I feel it is needed with our current world events. Before I get the "I'm going to stay off the grid" comments... I think you should know that most hams, (local and world-wide, think and talk like we do. If you get mail and have a driver's license, you are not "off the grid". My advice is to stay legal, get your license before you every key the mic on a ham frequency and get in a local club.
Last bit of advice. A cheap, dual band hand held (HT) is the Baofeng UV-5R as noted in a post up-thread. The newer versions of the UV-5R use different accessories (batteries, programing cables, etc...), so stick with the older UV-5R which has a proven track record.
And my last word on the subject...You don't have to learn Morse Code anymore!
